Here in Florida we got lots of bugs:frown: I have an old lawnmower that I got out of the trash, 3hp B&S with a rusty deck:thumbsup: so I put a little two stroke oil in the gas an push it around the yard the smoke seems to keep the bugs down when outside grilling food:licking:
I kept a Kawasaki 11HP (FE350), with very low compression and smoked a lot, running for another few years using Restore. I changed the oil and added an entire 4 cylinder can. There's not engine rebuilder in a bottle, but it works enough.
